Swimming Pool Door & Window Alarms

Add a critical layer of child safety protection with pool door and gate alarms that alert you the moment a door, window, or gate to the pool area is opened. PST Pool Supplies stocks pool access alarms from Poolguard and Smartpool (YardGard) — battery-powered, automatic-reset units that mount to gates, doors, and windows providing access to the pool, starting from $38.

The Poolguard GAPT Gate Alarm is a dedicated pool gate alarm engineered for outdoor gate installations — it triggers an audible alert when the gate is opened without first pressing the delay button on the interior side. The unit is weather-resistant, battery-powered, and automatically resets after the gate closes. The Smartpool YardGard Programmable Gate/Door/Window Alarm System is a versatile alarm that can be programmed for gates, doors, or windows providing pool access — multiple units can be installed throughout a property to cover all pool access points. YardGard includes programmable delay and sensitivity settings to reduce false alerts while maintaining reliable detection. Both products provide audible alarm notification to alert adults to unauthorized access before a child can reach the water. For pool perimeter safety fencing, browse our pool safety fence collection. Pool access alarm requirements vary by state and municipality — consult the Pool Safely program at the U.S. Consumer Product Safety Commission for your state's specific requirements.

Pool door and gate alarms are an important component of a layered pool safety strategy — but they work best in combination with other barriers, not as a standalone measure. The Pool Safely guidelines recommend: physical barriers (fencing with self-closing, self-latching gates), active supervision, swimming lessons for children, and alarm systems as supplementary alert mechanisms. Door and gate alarms alert you to access events but require an adult to hear and respond — they do not physically prevent access. Install alarms on every door and gate with access to the pool area including garage doors, sliding glass doors, windows, and fence gates. Test the alarm monthly to verify battery function and alarm audibility from your home's interior. In many states (including California, Florida, and Arizona), pool safety barriers and alarms for homes with young children are required by law.

Shop pool door and gate alarms and strengthen your pool safety barrier system with reliable audible alert technology.

Frequently Asked Questions

Are pool door alarms required by law?
Pool safety barrier requirements — including door and gate alarms — vary significantly by state and municipality. States with the most stringent requirements include California, Florida, Texas, Arizona, and New Jersey, which mandate specific combinations of barriers (fencing, self-latching gates) and may also require alarms for homes with young children or new pool construction. The Virginia Graeme Baker Pool and Spa Safety Act (federal) sets baseline standards for public pools. For residential pools, check your specific state and local building codes — requirements typically apply to new pool construction, home sales, or major renovation permits. Regardless of legal requirements, the U.S. CPSC Pool Safely program recommends pool door alarms as part of a comprehensive safety barrier system for any home with a pool and young children.
How does the Poolguard GAPT gate alarm work?
The Poolguard GAPT is a two-part magnetic contact alarm system. The main alarm unit mounts on the gate post or fence, and a magnetic actuator mounts on the gate itself aligned with the alarm unit. When the gate opens, the magnetic contact breaks and the alarm triggers an 85 dB audible alert within 7 seconds of the gate opening. To bypass the alarm for authorized adult access, press and hold the delay button on the interior side of the unit, which provides approximately 7 seconds of delay to open the gate without triggering the alarm. After the gate closes, the alarm automatically resets — no manual reset required. The unit is battery-powered (standard 9V battery) and is rated for outdoor use. Battery life is approximately 1 year with normal use. Test the alarm monthly by opening the gate without pressing the delay button to verify the alarm sounds and the battery is functional.
Can I use the YardGard alarm on a sliding glass door?
Yes — the Smartpool YardGard is specifically designed to work on gates, hinged doors, and sliding doors and windows, making it a versatile option for covering multiple pool access points with a single product line. For sliding doors, the alarm unit mounts to the door frame and the magnetic actuator mounts to the sliding door panel — when the door slides open, the magnetic contact breaks and the alarm activates. The YardGard includes programmable delay settings so adults can open the door deliberately without triggering the alarm, while unauthorized openings (like a child sliding the door open) immediately trigger the alert. Install one unit on each pool access point — sliding glass doors, windows, garage side doors, and fence gates — for comprehensive coverage. Multiple units from the same system type can be installed throughout the home independently.
Where should I install pool door alarms in my home?
Install pool door and gate alarms on every access point that leads directly or indirectly to the pool area. This includes: any door from the house interior directly to the pool or pool enclosure (sliding glass doors, French doors, back entry doors), any window in a room accessible to children that opens toward the pool area, all gate entrances in pool perimeter fencing (including side yard and garage pass-through gates), and any door between an attached garage and the pool area if the pool can be reached through the garage. Pool safety organizations recommend thinking like a curious child — identify all possible paths a child could take to reach the water and alarm each one. A pool access alarm on only one door provides false security if there are multiple other unalarmed access points. Layer your protection: fencing + self-latching gate + door alarms + active supervision is the recommended multi-barrier approach.
